A woman walks into a store and notices a shiny item on the shelf. She asks the sales clerk, “What is that shiny object?”
The clerk responds, “That is a thermos.”
Curious, the woman then asks, “What does it do?”
The clerk explains, “It keeps hot things hot and cold things cold.”
Impressed, the woman says, “Oh! That sounds useful! I’ll take one!”
The next day, she arrives at work with her new thermos and excitedly shows it to her boss. “Look at my new thermos! It’s amazing—it keeps hot things hot and cold things cold!”
Intrigued, the boss asks, “So, what do you have in it?”
The woman replies, “Some coffee and a popsicle.”
